Problems solved by technology

The disadvantage is that after the wool fabric is immersed in the flame retardant finishing solution twice, the wool fabric immersed in the flame retardant finishing solution first will absorb a large amount of flame retardant finishing agent, resulting in a decrease in the concentration of the flame retardant finishing solution, so that adsorption occurs in the traveling direction of the wool fabric. The concentration of the flame retardant finishing liquid on the wool fabric decreases, which eventually leads to the fluctuation of the flame retardant finishing effect in the length direction of the piece

Embodiment 1

[0014] The wool fabric is pulled to the cloth storage trough at 5 m / min, and then pulled to the bottom of the electromagnet by the active traction guide roller group in the flame-retardant finishing process. The magnetic force of the electromagnet is 784N, the weight of the dipping plate is 60kg, and the depth of the finishing liquid tank is 0.4 meters. The generated magnetic force lifts the iron dipping plate and holds the fabric between the electromagnet and the dipping plate. The clamping time is 0.5 Seconds, the flame retardant finishing agent is tetraethyl orthosilicate and ammonium dihydrogen phosphate compound gel, the electromagnet is powered off, stops working, the active traction guide roller in the flame retardant finishing process is energized to start working, and the fabric runs to the next step. A section of fabric finishing. The flame retardant effect of the fabric is shown in Table 1.

Embodiment 2

[0016] The wool fabric is pulled to the cloth storage trough at 25 m / min, and then pulled to the bottom of the electromagnet by the active traction guide roller group in the flame-retardant finishing process. The magnetic force of the electromagnet is 882N, the weight of the dipping plate is 65kg, and the depth of the finishing liquid tank is 0.5 meters. The generated magnetic force lifts the iron dipping plate and holds the fabric between the electromagnet and the dipping plate. The clamping time is 0.75 Seconds, the flame retardant finishing agent is tetraethyl orthosilicate and ammonium dihydrogen phosphate compound gel, the electromagnet is powered off and stops working, the active traction guide roller in the flame retardant finishing process is powered on and starts to work, and the fabric runs to the next stage. A section of fabric finishing. The flame retardant effect of the fabric is shown in Table 1.

Embodiment 3

[0018] The wool fabric is pulled to the cloth storage trough at 45 m / min, and then pulled to the bottom of the electromagnet by the active traction guide roller group in the flame-retardant finishing process. The magnetic force of the electromagnet is 980N, the weight of the dipping plate is 70kg, and the depth of the finishing liquid tank is 0.6 meters. The generated magnetic force lifts the iron dipping plate and holds the fabric between the electromagnet and the dipping plate. The clamping time is 1 Seconds, the flame retardant finishing agent is tetraethyl orthosilicate and ammonium dihydrogen phosphate compound gel, the electromagnet is powered off and stops working, the active traction guide roller in the flame retardant finishing process is powered on and starts to work, and the fabric runs to the next stage. A section of fabric finishing. The flame retardant effect of the fabric is shown in Table 1.

Abstract

The invention relates to an attraction type flame-retardant finishing method capable of achieving magnetic lifting of a bonding liquid for a fabric and belongs to the technical field of textiles. A finishing liquid tank adopted in the method is in a hollow shape and is movably provided with an iron bonding liquid plate, an electromagnet is fixedly arranged above the finishing liquid tank and corresponds to the iron bonding liquid plate, the surface area of the electromagnet is equal to that of the iron bonding liquid plate, the magnetic force of the electromagnet is in direct proportion to theweight of the iron bonding liquid plate and the depth of the finishing liquid tank, and the electromagnet and a driving guide roller group are separately connected to a stroke controller. According to the finishing method, the fabric is not directly in contact with a flame-retardant finishing liquid, the phenomenon that the concentration of the flame-retardant finishing liquid is changed since aflame-retardant finishing agent in the flame-retardant finishing liquid is excessively absorbed by the fabric cannot occur, and the situation that a flame-retardant finishing effect of the fabric is different due to the change of the concentration cannot be caused. Therefore, by adopting the technical scheme, the concentration of the flame-retardant finishing liquid in a flame-retardant finishingprocess is not changed, and convenience is provided for ensuring the consistency of the flame-retardant effect of the fabric.

Description

technical field [0001] The invention relates to a method for fabric magnetic force lifting and liquid absorbing flame retardant finishing, which belongs to the technical field of textiles. Background technique [0002] As consumers have higher and higher requirements for flame-retardant finishing of fabrics, the importance of flame-retardant finishing has also been paid more and more attention. The common process of flame retardant finishing is padding finishing process. Chinese Publication "Printing and Dyeing", published in Issue 11, 2014, the title of the article is Phosphorous Silica Sol Flame Retardant Finishing of Wool Fabric. This document introduces a method of flame retardant finishing of wool fabric. In the second rolling, the liquid carrying rate is 75%-80%. After the fabrics padded with the flame retardant finishing agent are prebaked and baked, the wool fabric shows a good flame retardant effect. The disadvantage is that after the wool fabric is immersed in t...
